Pay $30 and get your C&R FFL. No need to fill out a 5320.20 or worry if the state you're going to is NFA friendly or not.
Section 13.8. Requesting permission to transport certain firearms in interstate or foreigncommerce. A person, other than an FFL/SOT, may not lawfully transport in interstate or foreigncommerce any destructive device, machinegun, short-barreled shotgun, or short-barreled rifle, withoutprior written approval of ATF, specifically the NFA Branch.214 For definitions of these firearms anddevices, refer to 27 CFR 478.11. Licensed collectors are not required to obtain such approval if the firearms and devices being transported are “curio or relic” firearms under the GCA.
The primary impact of a curio or relic classification is that a properly registered NFA firearm classified as a curio or relic may be lawfully transferred interstate to, or received interstate by, a person licensed as a collector of curios or relics under the GCA.
Does the registered owner of a destructive device, machine gun, short-barreled shotgun, or short-barreled rifle need authorization to lawfully transport such items interstate?
Yes, unless the registered possessor is a qualified dealer, manufacturer or importer, or a licensed collector transporting only curios or relics. Prior approval must be obtained, even if the move is temporary. Approval is requested by either submitting a letter containing all necessary information, or by submitting ATF Form 5320.20, Application to Transport Interstate or to Temporarily Export Certain National Firearms Act (NFA) Firearms. This requirement does not apply to the lawful interstate transportation of silencers. Possession of the firearms also must comply with all State and local laws.
